(a) The Standard Industrial Classification (SIC) system has been replaced by the North
American Industry Classification System (NAICS).  Since the Bureau of the Census has collected
the information necessary to classify establishments on both an NAICS and an SIC basis, the same
1998 data can be shown on both the old and the new basis in bridge tables that allow comparisons
between the two systems.  These data are hereby produced for the last time on an SIC basis for
1998 at the national level only.
NF=No applicable RSE row/column factor.
* Estimate less than 0.5.
W=Withheld to avoid disclosing data for individual establishments.
Q=Withheld because Relative Standard Error is greater than 50 percent.
NA=Not available.
Notes:  To obtain the RSE percentage for any table cell, multiply the cell's
corresponding RSE column and RSE row factors.   Totals may not equal sum of
components because of independent rounding.   The estimates presented in this
table are for the total consumption of energy (formerly total inputs of energy)
for the production of heat, power, and electricity generation,
regardless of where the energy was produced.  Specifically, the estimates
include the quantities of energy that were originally produced offsite and
purchased by or transferred to the establishment, plus those that were produced
onsite from other energy or input materials not classified as energy, or were
extracted from captive (onsite) mines or wells.
During manufacturing processes, it is possible that the thermal energy content of
an energy input is not completely consumed for the production of heat,
power, or electricity generation.  Hence, residuals of that input may
remain.  Those residual leftovers may be subsequently consumed for fuel
purposes, whether onsite or offsite at another manufacturing establishment
(for example, blast furnace gas as a byproduct recovered from coke and
other inputs that were not completely consumed).  In such cases, double
counting of inputs cannot be avoided, and the "Fuel Consumption" estimates will
be inflated.
